Abstract: In one aspect, the invention relates to a method of treating infectious bursal disease (IBD) in an avian subject in need of such treatment. The method comprises administering to the subject a compound of the formulas (I) through (IV) or a pharmaceutically acceptable salt thereof in an amount sufficient to treat IBD. In another aspect, the invention relates to a method of producing active immunity against infectious bursal virus disease (IBD) in an avian subject. The method comprises administering to a subject an immunogenic-amount of an IBDV vaccine and a compound selected from the compounds of formulas (I) through (IV) described herein. The compound represented by formulas (I) through (IV) is administered in an amount sufficient to induce an immune response in the avian subject.

Abstract: A method and apparatus for automatically and rapidly, retrieving, counting and/or analyzing at least one selected population of cells or formed bodies, such as a white blood cell population and at least one subset thereof of a whole blood sample or portion thereof. A volume of a biological medium containing the white blood cells is prepared and at least one reactant specific or preferential at least to some selected biological cells is introduced thereto and rapidly mixed for a short period of time. The opacity and/or volume parameter of the cells can be modified and the mixture is then counted and analyzed in one or more steps to obtain the desired white blood cell population and subset analysis. The biological sample can be a whole blood sample and the reactant can include or be a lyse or a monoclonal antibody bound to microspheres, which will bind to specific ones of the cells or a combination of lyse and microspheres with antibody bound thereto.

Abstract: A table for a saw has three equal table segments supported on foldable legs. The three segments are spaced from one another by spacer elements and held in position by front and back longitudinal rails and nut and bolt combinations through the spacer elements. The spacer elements hold the table segments spaced from one another thereby defining first and second lateral slots within which the rail of a mitre gauge can ride. Four spacer elements are integral parts of a spacer bar. Each spacer bar has laterally spaced spacer elements and vertically spaced spacer elements thereby providing numerous accurately dimensioned spacing locations between adjacent table segments. The spacer elements and longitudinal rails in combination establish table element positioning and rigidity with respect to one another as well as established two longitudinal slots having a uniform predetermined width.
